FIELD OF THE INVENTION

The present invention relates to a petroleum analytics learning machine system and method to maximize production from wells of oil and natural gas fields while minimizing costs.

OBJECT AND A SUMMARY OF THE INVENTION

The Petroleum Analytics Learning Machine (PALM) is a machine learning based, “brutally empirical” analysis system for use in all upstream and midstream oil and gas operations. The Petroleum Analytics Learning Machine™ is a trademark of applicant. The objective of the PALM is to become the go-to ‘brain’ of oil and gas exploration and production, including drilling, completion, and pipeline gathering operations. The PALM was reduced to practice primarily in the new unconventional shale oil and gas play. The PALM analyzed more than 100 attributes integrated from all available data referenced above, in more than 150 horizontal wells and more than 2000 hydraulic fracture (frac) stages that were drilled since 2012 in the wet gas region of the Target Layer shale of Pennsylvania. The PALM was also validated in more than 3000 shale oil wells with more than 10,000 hydraulic fracture stages in the Permian Basin of Texas. In accordance with an exemplary embodiment of the claimed invention. The PALM comprises Machine Analytics Products™ (MAP) Application subsystems (subsystems) that are big-data-centric, using computational machine learning predictive and prescriptive analysis techniques to maximize production of hydrocarbons while minimizing costs of oil and gas upstream exploration and production (E&P) and midstream pipeline operations.

In accordance with an exemplary embodiment of the claimed invention, the PALM comprises MAP subsystems for geology, geophysics, reservoir modeling and rock physics, MAPGEORES; drilling, MAPDRILL; hydraulic fracturing and completions, MAPFRAC; production of hydrocarbons including oil and other liquid condensates, natural gas, and water, MAPPROD; and gathering pipelines and compressor stations, MAPGATHER. In accordance with an aspect of the claimed invention, PALM further comprises other MAP subsystems, such as portfolio management, MAPPORTFOLIO; and others subsystems specifically developed for a customer and the like. These subsystems use the PALM System Integration Database (SID) to retrieve integrated data, then perform machine learning and other statistical analyses of that data, and return to the SID results of computation and predictive and prescriptive actions that can be forwarded by the TOTALVU user interface (UI) to controllers, human and/or automated, so that real-time optimization of production and minimization of costs can be realized for new wells. The unique PALM product suite was developed by inventing scientists and engineers with more than 80 years of combined energy industry expertise, working alongside big data scientists experienced in building real-time decision and control systems. The PALM predictive and prescriptive technologies utilize Support Vector Machine learning, time-series shape recognition, and real-time Random Forest and decision trees to steer hydraulic fractures to become more likely high instead of low producers, stage by stage, as completions of horizontal and vertical shale wells progress. The PALM also uses Support Vector Regression, logistic regression, Bayesian models, nearest neighbors, neural networks and deep learning networks uniquely combined as ensemble learning to weigh the importance of hundreds to thousands of geological, geophysical, and engineering attributes, both measured in the field and computed from theoretical analyses such as reservoir simulation models and 4D seismic and gravity gradiometry monitoring of production changes over time.

In accordance with an exemplary embodiment of the claimed invention, a system and method for optimizing exploration, production and gathering from at least one well to all wells of oil and natural gas fields using a Petroleum Analytics Learning Machine system to maximize production while minimizing costs is provided. Structured digital data and unstructured textual data from geological, geophysical, reservoir modeling simulation, drilling, hydraulic fracturing and completion, and production of crude oil, natural gas, ethane, butane, propane and condensates are collected.

The incoming data comprises digital exogenous data, real-time and historical endogenous data, historical data from surrounding production wells, hydraulic fracture completion data, and progress, status and maintenance data from new vertical and horizontal wells, including kickoffs, sidetracks, step-outs, pipeline gathering systems, compressor stations and other kinds of oil and gas sensor data including from public and private data sources now existent and of future design. The time and depth for each data point of the collected data are recorded. The collected data are ‘cleaned’ to eliminate extraneous and noisy data. The cleaned data are normalized and stored. The normalized data are processed to determine clusters of correlation in multi-dimensional space to identify a machine learned ranking of Importance Weights for each attribute. The Importance Weights are convolved with specific well weights to identifying patterns to enhance production of at least one well or all wells of oil and natural gas fields.

In accordance with an exemplary embodiment of the claimed invention, the aforesaid system and method provides real-time recommendations to minimize sinuosity of horizontal wells while maintaining a position within selected landing zones for predetermined distances.

In accordance with an exemplary embodiment of the claimed invention, the aforesaid real-time processor independently monitors the completions data. The completions data comprises perforation depths and time, completions tool use and choke setting. Also, the completions data comprises at least one of the following: time series hydraulic fracture data including surface and downhole pressures, slurry compositions and water mixes, sand volumes, breakdown pressure, proppant concentrations and shut-in pressure for each hydraulic fracture. The aforesaid system and method optimizes a maximum possible production from one or more hydraulic fracturing stages while minimizing its costs by a real-time processing and generation of a predictive machine learning model based on classification of the key attributes determined by the Petroleum Analytics Learning Machine system. A time of a density drop that ends a first sand injection is one of the key attributes. A pressure percentile at the time of the first density drop is one of the key attributes. A time of a density drop that ends a second sand injection with sand larger in diameter and heavier than the sand used in the first sand injection is one of the key attributes. A pressure percentile at the time of the second density drop is one of key attributes. A time of a pressure drop at an end of a shut-in is one of the key attributes. A pressure percentile at the time of the pressure drop at the shut-in is one of the key attributes.

A time of a beginning of a sand change from a lighter to the heaviest sand is one of the key attributes. A pressure percentile at beginning of a heaviest sand density increase is one of the key attributes. A time of a highest pressure after the sand change to the heaviest sand is one of the key attributes. A pressure percentile of a maximum heaviest sand change is one of the key attributes.

A scatter of the linear regression of the pressure from the beginning of the heaviest sand injection to the highest pressure at the end of the heaviest sand injection is another of the key attributes.

In accordance with an exemplary embodiment of the claimed invention, the aforesaid real-time processor generates one or more real-time executable recommendations to a hydraulic fracturing control center. The real-time executable recommendations comprises at least one of the following: a recommended down-hole pressure, a proppant concentration, slurry rate and volume, and a water/sand mix based on at least trends in one or more hydraulic fracturing decision tree and random classifications of historical, highly productive versus low producing stages.

In accordance with an exemplary embodiment of the claimed invention, the aforesaid system and method generates one or more conditions to change real time decisions in the hydraulic fracturing control center based on updated decision trees and random forest predictions that can steer in real time towards a high producing fracture versus a low producing fracture stage.

In accordance with an exemplary embodiment of the claimed invention, the aforesaid real-time processor executes automated time series classification using a machine learning feature recognition to develop clusters of hydraulic fracture classes. The aforesaid real-time processor correlates stages of each class to an average highest production of historical wells. The automated time series classification comprises multiple hydraulic fracture classifications. FracClass 1 is a failure to fracture due to surface equipment failures resulting in no hydraulic fracture and no input to a well production. FracClass 2 is a hydraulic fracture but a subsequent equipment failure either on the surface or down-hole results in a minimal sand displacement and a hydraulic fracture is cut short by an operator, and a current stage is cancelled and moves on to a next stage in the well production plan. FracClass 3 is a successful fracture at extended time and cost, a rapid sand injection results in the well being accidentally packed-off to the surface by an excessive sand buildup. A wellbore is cleanup with water and re-perforated to allow a formation to take scheduled proppant sands in FracClass 3. FracClass 4 is a successful fracture and injection of a full planned for amount of sand, but a late sand placement at an end of a proppant injection results in a pressure surge. In FracClass 4, the heaviest sand injection sand placement is only pack-off locally to a near wellbore annulus of perforations of the current stage and a subsequent water cleanout fails to washout the near wellbore sand placement away from the annulus. FracClass 5 is a perfect hydraulic fracture. In FracClass 5, the full planned amount of the sand is emplaced in a scheduled time, and a subsequent water wash successfully washes the sand from the drill pipe, but also unfortunately the formation in the near wellbore, disrupting connectivity to the hydraulic fracture proppants deeper into the formation.

In accordance with an exemplary embodiment of the claimed invention, the aforesaid real-time processor performs the automated time series classification by discovering sequential patterns and interactions among time series variables utilizing at least one of the following: an autoregressive integrated moving average (ARIMA) model, a multivariate time series analysis, a hidden Markov model, an autoregressive conditional heteroskedasticity (ARCH) model, an exponentially weighted moving average and a generalized autoregressive conditional heteroskedasticity (GARCH) model.

In accordance with an exemplary embodiment of the claimed invention, the aforesaid real-time processor generates one or more executable recommendations to proceed to a productive hydraulic fracture class mixture based on tornado diagrams utilizing the machine learning to match clusters of attributes of the hydraulic fracture classes that correlate with a maximum production. The aforesaid system and method generates recommended actions to control the hydraulic fracture classes or FracClasses 3 and 4 occurrences as a percentage of the hydraulic fracture class or FracClass 5 of perfect factures. In accordance with an exemplary embodiment of the claimed invention, the aforesaid system and method automatically updates the decision trees to estimate limits of combination of the down-hole pressure, the proppant concentration, the slurry volume and rate, and a sand volume and size based on trends in one or more historical hydraulic fracture successes and failures that occur in each well stage-by-stage, and automatically convey by self-driving, autopilot and/or other autonomous means directions of future actions to the controller of hydraulic fracturing.

In accordance with an exemplary embodiment of the claimed invention, the aforesaid real-time processor stores the hydraulic fracture classes from each new well in the system integration database, thereby enabling subsequent production of liquids, gas and water to be tested against stored hydraulic fracture class mixtures, real-time conditions, and performance measurements as fractures unfold in real-time.

In accordance with an exemplary embodiment of the claimed invention, the aforesaid real-time processor generates one or more hydraulic fracturing conditions that minimizes ideal hydraulic fracturing conditions comprised by at least reducing costs of a service company's time and energy. The aforesaid system and method determines a proppant and water consumption and recommends a decision to proceed or stop said each hydraulic fracturing stage because cost exceeds benefit.

In accordance with an exemplary embodiment of the claimed invention, the aforesaid real-time processor comprises a memory to store computer-executable instructions. The aforesaid real-time processor is coupled to at least one transmitter to communicate with the hydraulic fracturing control center via a bi-directional messaging interface. The aforesaid real-time processor executes the computer-executable instructions to cause the hydraulic fracturing control center (or Frac control center) to perform multiple actions. The hydraulic fracturing control center receives recommendations from the Petroleum Analytics Learning Machine system. The Frac control center generates at least one recommendation to increase production or cut costs of a well in progress by controlling a mix of the hydraulic fracturing class outcome using decision trees of the Petroleum Analytics Learning Machine system to maximize an overall ell production. The Frac control center stores data from actions undertaken based on at least one recommendation in the system integration database to provide a feedback to the Petroleum Analytics Learning Machine system about its recommendations based on the future production.

In accordance with an exemplary embodiment of the claimed invention, the aforesaid real-time processor computes a forecast for production of oil, natural gas, gas liquids, and water for a duration of a profitable history of a well, before delivery of the oil and gas to the surface. The aforesaid real-time processor continuously monitors and updates the production as the well ages. The aforesaid real-time processor provides an estimated ultimate recovery modification recommendations when a deviation from a forecasted, estimated ultimate recovery is predicted.

In accordance with an exemplary embodiment of the claimed invention, the aforesaid real-time processor analyzes a pipeline gathering system that is monitoring data from maintenance and “pigging” (self directed or flowing cylinders of electronics that are pumped through the inside of the pipeline to make measurements of corrosion, fracturing, liquids and water buildup, and other unsafe conditions within the pipeline) and storing it in the system integration database. The monitoring data comprises at least one of the following: time series of nodal pressure, liquids and gas compositions and volumes, maintenance records; and the PALM system identifies correlation clusters to predict optimal pigging schedules and looping directions for highest performance of a pipeline gathering system.

A composite tornado plot is then created for seasons, wet versus dry and hot versus cold. Forecasting of day-ahead and week-ahead pipeline gathering system capacity leads to the identification of maintenance that will prevent the need to shut-in wells because of excessive gathering system capacity. Ranking by section of good to bad performing pipeline sections allows forecasting of susceptibility to liquids trapping, actual versus planned pigging success, witches hat problem events before they happen, and condensate restrictions needed to reduce actual/predicted production.

In accordance with an exemplary embodiment of the claimed invention, the MAP subsystem further comprises an Efficient Frontier Portfolio application to quantify outstanding cost/benefit that will then be calculated by the PALM system. Control is multi-objective; that is, it must optimize a combination of capital cost, reliability, operational cost, safety, as well as profitability, etc. The infrastructure management has to accommodate market signals that are stochastic and other exogenous variables that are also stochastic such as weather and environmental concerns. The state space for control is large, but handled by the PALM machine learning in order to provide optimal cost benefit control of the energy infrastructure of oil and gas fields.

Various other objects, advantages and features of the present invention will become readily apparent from the ensuing detailed description, and the novel features will be particularly pointed out in the appended claims.

DETAILED DESCRIPTION OF THE EMBODIMENTS

This application incorporates each of the following application by reference in its entirety: U.S. Pat. Nos. 6,826,483, 7,395,252, 8,036,996 B2, and 8,560,476.

Turning to FIG. 1, there is illustrated a general overview of the system incorporating the PALM 1000. In accordance with an exemplary embodiment of the PALM 1000 comprises a processor 1100, a machine analytics products (MAP) 1200 subsystems, as well as a System Integration Database (SID) 1300, a Machine Learning Optimizer 1400, and a TotalVU controller 1500 providing data visualization.

As shown in FIG. 2, in accordance with an exemplary embodiment, the PALM system 1000 feeds data to and archives analyses results from MAP 1200 subsystems, including but not limited to: MAPGEORES 1210, MAPDRILL 1220, MAPFRAC 1230, MAPPROD 1240, MAPGATHER 1250 and MAPPORTFOLIO 1260. The PALM Processor 1100 comprises a Machine Learning optimizer that predicts future results and prescribes actions to improve performance, and interacts with the operator via the TotalVU controller 1500 and its associated user interface.

In accordance with an exemplary embodiment of the claimed invention, the MAPGEORES 1210 is a geologic, geophysical, rock properties, and reservoir modeling engine that scores the Importance Weights calculated by the Machine Learning Optimizer 1400. Specifically, the predictor 1410 and prescriptor 1420 of the Machine Learning Optimize 1400 uses an ensemble of cluster and classification analyses in order to predict maximum production before a well is produced to the surface.

In accordance with an exemplary embodiment of the claimed invention, the MAPDRILL 1200 is a real-time drilling data integration engine that optimizes drilling to match the designed pathway of the well including hitting one or more landing zones, while minimizing sinuosity of horizontal and non-vertical components of the drilled well.

In accordance with an exemplary embodiment of the claimed invention, the MAPFRAC 1230 is a real-time hydraulic fracture classifier used to control the class of hydraulic fractures (FracClass) stage-by-stage, onsite or off. MAPFRAC 1230 uses the FracClass classification system of the claimed invention to predict the optimal mixture of perfect fracture stages (not good for production if all stages of a horizontal lateral length are perfect, a surprise discovery of the claimed invention), versus the class of frac' s that deliver late stage sand placement more effectively to the near wellbore. Inventors discovered that more than 25% of these imperfect frac's out produced perfectly frac'ed wells in our reduction-to-practice example. Other FracClasses identified by the PALM system 1000 deal with the inevitable surface and wellbore mechanical failures that occur in order to make decisions when to abandon a costly frac to minimize losses.

In accordance with an exemplary embodiment of the claimed invention, the MAPPROD 1240 is a production forecaster that convolves the actual attribute values of hundreds to thousands of attributes coming into the system from historical wells, as well as each new well as it progresses, to maximize production for all wells in a play. The result, as controlled by the actions recommended by the PALM 1100 processor, is the optimization of the production of oil, natural gas, and natural gas liquids while minimizing water production (a cost) over time.

In accordance with an exemplary embodiment of the claimed invention, the MAPGATHER 1250 integrates the pipeline field data from gathering pipelines and production facilities, a real-time system for optimizing maintenance and pigging schedules, while minimizing liquids dropout in order to maximize fluid and gas throughput of the pipeline gathering system.

In accordance with an exemplary embodiment of the claimed invention, the MAPPORTFOLIO 1260 manages the efficient frontier of costs versus benefits for each well, field, play or company, and the MAP ETC. 1270 is a subsystem or an application engine specifically built to address a particular situation or customized for a specific customer's need or requirement.

Turning now to FIG. 3, in accordance with an exemplary embodiment, there are listed machine analytics algorithms and tools commonly accessible to all MAP 1200 subsystems within the PALM 1000. The Machine Learning Optimizer 1400 computes adaptive stochastic control, locally sensitive hashing, and MapReduce parallelization in Hadoop. Unstructured Analyses 1401 extract, retrieve and mine information from text, perform entity and pattern recognition, log-rank, perform keyword extraction, semantic analysis, knowledge discovery, sentiment analysis and noisy text processing. A Clustering Predictor 1410 computes K-means, K-medoids, region growing, and non-parametric modeling. A Regression Predictor 1411 computes linear and support vector regression, and classification and regression trees (CART). A Feature Selector 1412 computes and ranks Importance Weights, Chi-square goodness of fit, Fischer score probabilities, principal component analysis (PCA), and contains various wrapper methods. An Ensemble Prescriptor 1420 computes bagging, mountain climbing optimization, boosting of aggregate classifiers, random forest decision trees, and gradient boosters. A Classification Prescriptor 1421 computes logistic regression, support vector machines, K-Nearest neighbor, Decision tree modeling, and Neural networks and Deep learning. A Time Series Prescriptor 1422 computes Multivarieant time series, Hidden Markov models, and non-parametric Bayesian models.

In accordance with an exemplary embodiment of the claimed invention, as shown in FIG. 4, the system integration database (SID) 1300 is the central data repository for all data sources. The SID is a multi-architectural data center that incorporates components of different database technologies. One component is based on relational database management system (DBMS), which is for the traditional structured column based data management. The SID 1300 also features a NoSQL data management, which provides a mechanism for storage and retrieval of data not only in tabular relations. For example, textual data, such as PDFs, image data such as frac's, audio and video data can be analyzed via the NoSQL architecture for storage, and efficient retrieval. An example NoSQL database is MongoDB. Another component of the SID 1300 is a distributed file system. In the petroleum industry, terabytes of data are generated every day, such as time series hydraulic fracture data, well log and measurement-while-drilling data, and sensor data that monitors production and delivery to processing plants. How to store these data, and make use of such large-scale data poses a challenge in this domain. A distributed file system facilitates the storage and maintenance of the data, and provides efficient data computations and analytics. For example, Hadoop is a framework that allows for the distributed storage of data and distributed processing of large data sets across clusters of computing resources. A component of the SID 1300 makes use of Hadoop distributed file system (HDFS) for data storage, and MapReduce techniques for further data learning and computation. The large-scale data analytics in oil and gas benefit from the recent development of big-data technologies. Hadoop ecosystem is a framework that is based on the MapReduce algorithm for big data analytics. Hadoop distributed file system (HDFS) stores large-scale of data in a distributed network across computing clusters. Data computation is performed on each computing node in the Map step, and an intermediate output is combined to perform a global computation in the Reduce step.

Within the SID 1300, in accordance with an exemplary embodiment of the claimed invention, exogenous data 1360 include primarily weather history and future forecasts.

In accordance with an exemplary embodiment of the claimed invention, the MAPGEORES 1210 computes production forecasts entirely from geological, geophysical, rock property and reservoir simulation data known before the well is spudded. The tornado diagram of importance weights calculated by MAPGEORES 1210 as exemplary displayed by the TotalVU 1500 is shown in FIG. 5. The calculated importance weights are used by the PALM 1000 to predict production accuracy in accordance with an exemplary embodiment of the claimed invention. Appendix 1 is a list of attributes shown in FIG. 5 ranked by their importance weights calculated by MAPGEORES 1210 using Support Vector Regression. The prediction of production of oil, natural gas and water when Importance Weights were convolved with the same labeled attributes specific to each well were found to be 67% accurate using this initial set of geology, geophysics, rock properties, and reservoir modeling attributes.

The MAPGEORES 1210 utilizes machine learning of the historical structured data to compute Importance Weights for the attributes that represent all the data available before spud. The machine learning algorithms of the MAPGEORES 1210 uniquely combine the parameters of support vector and linear regression, allowing the construction of the Tornado diagrams, as exemplary shown in FIG. 5, to represent the Importance Weights of each attribute that correlates with a positive production prediction result (the bars to the right) and the importance of negative weights of each attribute that correlates with a positive production prediction result (the bars to the left). The predicted production is then compared to the actual production to derive an accuracy score. The future production accuracy is approximately 67% for the reduction-to practice shown in FIG. 5, whereas a random forecasting would be accurate only 50% of the time.

In accordance with an exemplary embodiment of the claimed invention, the MAPGEORES 1210 assembles a wide array of unstructured textual and image data (such as .pdf) to create additional attributes that are included in the machine learned ranking of Importance Weights, forming new attributes such as exemplary shown in Table 1.

In accordance with an exemplary embodiment of the claimed invention, the MAPDRILL 1200 is a real-time synthesizer of the data coming into the SID 1300 during the drilling process, which can be 2000 or more data points each second. The MAPDRILL 1200 optimizes the drilling to match as closely as possible the designed pathway of the well including hitting one or more landing zones, while minimizing sinuosity of horizontal and non vertical components of the drilled well. In accordance with an exemplary embodiment of the claimed invention, the MAPDRILL 1200 minimizes the sinuosity of the horizontal component during the drilling of wells by monitoring and prescribing latitude, longitude and depth modifications to the inertial navigation steering mechanism. The larger the amplitude of the sinuosity of the horizontal well, or how much it deviates from the planned target path of the well, the more chances for liquids to pool in the valleys of the wellbore, which often can block the path of the liquids and gases to the surface. In accordance with an aspect of the claimed invention, the drilling console of a modern horizontal drilling rig receives data transmitted in near real-time from downhole, thereby allowing the driller to steer the horizontal well to prevent it from sinusoidal spiraling which can cause oil to have difficulty drilling to the surface.

In accordance with an exemplary embodiment of the claimed invention, the automated classification of hydraulic fracturing data by the MAPFRAC classifier 1230 to isolate a FracClass 4 hydraulic fracture, as illustrated in FIG. 6A, that is struggling to inject the last of its heaviest proppant, compared to a more “perfect” FracClass 5 frac that did not inject enough of the heaviest sand and proppant to cause the late pressure rise, as illustrated in FIG. 6B. The inventors discovered that a mix of FracClass 4 and 5 is required to produce a most productive well.

MAPFRAC classifier 1230 utilizes machine learning methods to classify the wells to be those with highest production versus lowest production. Attributes for machine learning include data sources in addition to geology, geophysics, rock properties, reservoir simulation, such as landing zones, stress gradients and other hydraulic fracturing attributes we invented such as FracClass completion classes. The total oil, gas, condensate, and water production, and their normalized production by flow days, normalized for perforated lateral length, are used as response variables. Classification methods such as logistic regression, naïve Bayes, support vector machine, decision trees (e.g. CART, ID3, C4.5, CHAID), k-nearest neighbors, neural networks and deep learning networks are used by the MAPFRAC classifier 1230. Prediction accuracy, precision, and recall for each class are metrics used by the PALM 1000 to evaluate the production forecasting performance. Regression models such as linear regression, support vector regression, classification and regression trees (CART) can be also used by the MAPFRAC classifier 1230. R-Square, mean square error, among others, can be used to evaluate the regression performance. If a ranking is generated by the MAPFRAC classifier 1230 where the top of the rank list are high producing wells, and the bottom are low producing wells, receiver operating characteristic (ROC) curves and area under the ROC curve (AUC) are used to evaluate the ranking performance.

In accordance with an exemplary embodiment of the claimed invention, the ensemble methods that combine multiple classifiers can be used by the PALM 1000 to improve the overall robustness and reliability of the model. These ensemble methods include Ada boost, random forest, gradient boosting machine, and other bagging, and boosting techniques. The MAPFRAC classifier 1230 executes a unique automated time series classification schema using machine learning feature recognition to develop clusters of hydraulic fracture classes unique to the claimed invention, and then correlates the abundance of stages of each class to highest production of each well, as shown in Table 2.

TABLE 2 MAPFRAC Machine Learning Steps for FracClass Automated Classification of Hydraulic Fractures as illustrated in FIG. 7 (1231) Automatically select time of the beginning of sand change to heaviest sand proppant = timeheavysandstart. (1232) Automatically select pressure percentile at beginning of heaviest sand density increase = % pressureheavysandstart. (1233) Automatically select time of the density drop at the end of the heaviest sand injection = timedensitydropheavysandend. (1234) Automatically select pressure percentile at the time of the end of the heaviest sand injection = % pressuredropheavysandend. (1235) Automatically calculate the slope of the linear regression of the pressure from beginning of heaviest sand injection to the end of the heaviest sand injection = slopepressureheavysand. (1236) Automatically calculate the intercept of the linear regression of the pressure at the end pressure of the heaviest sand injection = Interceptpressureheavysand. (1237) Automatically assign a FracClass for each Hydraulic Fracture based upon whether the Slope (1235) at the Intercept (1236) is positive, wherewith the Hydraulic Fracture is assigned a classification of 4, representing a struggle to inject the last of the heaviest sand into the rock formation = FracClass 4, or (1238) Automatically assign a FracClass for each Hydraulic Fracture based upon whether the Slope (1235) at the Intercept (1236) is zero to negative, wherewith the Hydraulic Fracture is assigned a classification of 5, representing no struggle to insert the last of the heaviest sand into the formation = FracClass 5. (1239) Automatically calculate a statistical root mean squared scatter of the linear regression of the pressure from the beginning of heaviest sand injection to the highest pressure = rsquared.

The claimed invention has solved the problem of not knowing what production comes from which hydraulic fracture, stage-by-stage, by automating a classification scheme that the MACFRAC classifier 1230 correlates with high versus low production using at least 150 historical wells and at least 2000 hydraulic fracture stages per play in shale oil and gas basins around the world. FracClass 1 in the claimed classification schema is an incomplete fracture attempt that must be removed from the analysis dataset. FracClass 2 fracs were either “Emergency Shut Downs” (ESD) because of surface equipment failures, frac jobs cut short for any surface reason such has lightning and bad weather, or equipment shutdown (SD) that resulted in a full job but not a successful frac. FracClass 3 fracs were successful, but only after re-perforations that were required by the sand sweep resulting in the whole wellbore being packed off with sand. The most successful FracClass 4 fracs occurred when more that one quarter of the stages in a horizontal well resulted in late injection pressure rises at the near wellbore due to struggles to place the full allotment of late sand proppant.

A majority of FracClass 4 fracs correlated with subsequent high well production, surprisingly. FracClass 4 fracs can be independently identified within the completions data by the real-time processor, the completions data comprising time series hydraulic fracture data including surface and downhole pressures, slurry compositions and water mixes, sand volumes and proppant weights, breakdown pressure, proppant concentrations and shut-in pressure for each hydraulic fracture. A time of a density drop that ends a first sand injection 1231 is one of the key attributes. A pressure percentile at the time of the first density drop 1232 is also one of the key attributes. A time of a density drop that ends a second sand injection with sand larger in diameter and heavier than the sand used in the first sand injection is one of the key attributes 1233. A pressure percentile at the time of the second density drop is one of key attributes 1234. A slope in the time of a pressure drop at an end of shut-in is one of the key attributes. Automatic calculation of the slope of the linear regression of the pressure from beginning of heaviest sand injection to the end of the heaviest sand injection at the end pressure of the heaviest sand injection 1235, and comparison to the end of the proppant injection 1236 ends the slope fit. Automatic assignment of a FracClass for each Hydraulic Fracture is based upon whether the Slope at the Intercept is positive 1237, wherewith the Hydraulic Fracture is assigned a classification of FracClass 4, representing a struggle to inject the last of the heaviest sand into the rock formation, or the Slope at the Intercept 1238 is zero to negative, wherewith the Hydraulic Fracture is assigned a classification of FracClass 5, representing no struggle to insert the last of the heaviest sand into the formation.

That is, a time of a beginning of a sand change from a lighter to the heaviest sand is one of the key attributes. A pressure percentile at beginning of a heaviest sand density increase is one of the key attributes. A time of a highest pressure after the sand change to the heaviest sand is one of the key attributes. A pressure percentile of a maximum heaviest sand change is one of the key attributes. A slope of a linear regression of a pressure from beginning to end of the heaviest sand injection is one of the key attributes. An intercept of the linear regression of pressure from the beginning of the heaviest sand injection to the highest pressure at the end of the heaviest sand injection is one of the key attributes. The measure of scatter of the linear regression of the pressure from the beginning of the heaviest sand injection to the highest pressure at the end of the heaviest sand injection from stage to stage is another of the key attributes.

The MAPFRAC classifier 1230 discovered that horizontal shale oil and gas wells with more than 75% “textbook perfect” FracClass 5 hydraulic fracture stages produce less oil and gas than wells with less than 75% of FracClass 5 fracs and more abundance of FracClass 3 and 4 hydraulic fracture stages produce more oil and gas. The MAPFRAC result of intentionally increasing the FracClass 4 hydraulic fracture percentage per well in a drilling program in 2013 versus the preponderance of more “perfect” FracClass 5 wells from the 2009-2012 drilling program is exemplary shown in FIG. 7. In fact, the PALM 1000 predicted up to 320% improvement in oil production by increasing the FracClass 4 hydraulic fractures. This discovery was made in wells completed from 2009 through 2012, as shown in FIG. 7, where there was an improvement from the high cost perfect FracClass 5 dominated wells (diamonds of group 1 inset), to the medium to low cost FracClass 3 and 4 dominated wells (circles and triangles of groups 2 and 3 respectively). The high cost label for Group 1 diamond wells was because the hydraulic fractures cost the same, but the production benefit was diminished when compared to the Group 2 medium cost circle wells and low cost triangle wells. Average production for the 29 high cost wells was 2600 bbl/day, but 3500 bbl/day for 39 medium cost wells and 3600 bbl/day for 28 low cost wells, as they produced from 2009-2012. In 2013, a concerted effort was made to drill a blind test of wells dominated by FracClass 3 and 4 hydraulic fracture stages (squares). Twenty wells produced an average of 6150 bbl/day, for a production performance improvement over the “perfect” wells of 225%.

FIG. 8 illustrates a Tornado Diagram of the Importance Weights of MAPFRAC hydraulic fracture attributes that likely caused improvement in production for 2013 drill program shown in FIG. 7. Appendix 2 is a glossary of the top 20 attributes in FIG. 8. In accordance with an exemplary embodiment of the claimed invention, the MAPFRAC classifier 1230 identified improvements in production in 2013 by Importance Weights; better drilling into the targeted, deeper landing zone, a larger number of hydraulic fracture stages, longer perforated lateral length of the horizontal wells, and more total sand proppant injected into the formation during hydraulic fracturing, in that order. The FracClass 4 (the more the better) and FracClass 5 (the fewer the better) were ranked 13th and 14th most Important Weights, indicating they are dependent variables to the higher ranked independent variables listed above plus shorter perforation cluster and hydraulic fracture spacing used in 2013.

In accordance with an exemplary embodiment of the claimed invention, as illustrated in FIG. 9, the steering of hydraulic fractures to the more advantageous FracClass 4 fracs can be controlled from the “Frac Control Center” in real time using Random Forrest decision trees calculated by the MAPFRAC classifier 1230, which recomputes the “yes/no, if/then” branching of the tree every few seconds during each new frac. The boxed paths in FIG. 9 predict how to make a FracClass 4 instead of a FracClass 5 dominated oil well mix, which produced a much higher volumes of oil in FIG. 8.

As each hydraulic fracture proceeds from light sand to heaviest sand proppant, first the slope of the pressure is monitored. Successful FracClass 4 fracs can be obtained whether the slope is equal to or less than 0.15, in which the left branches (1249, 1247) of the Decision Tree become critical, or the slope is greater than 0.15, in which the right branches are critical. If the frac follows the rightmost branches (1248) of FIG. 9, the percentage pressure drop during injection of the heaviest sand proppant then becomes critical. If the percentage is less than 48%, the tree branches to the left (1247), and maximum pressure of the heavy sand proppant injection must be kept less than 98%. A FracClass 4 will then have a 90% success rate. If the pressure increases to more than 100% of what it has been, then the odds for a FracClass 5 frac are greater than 80%. If the percentage pressure drop is greater than 48% however, the rightmost decision tree branches will be followed. Then the slope of the pressure of heaviest sand proppant injection must be maintained at <=40% in order to have an 80% chance of developing a FracClass 4 frac.

If the slope of the initial pressure of the heaviest sand proppant is less than 0.15, then there is a 2;1 chance that the leftmost branches (1249) in FIG. 9 will be followed. Then the percent pressure drop of the heaviest sand proppant injection must be kept higher than 56% in order to be certain of a FracClass 4 frac.

FIG. 10 is illustration of the MAPPROD Tornado Diagram of Importance Weights that predict oil, gas and water production using all of the attributes available before production of first oil to the surface in accordance with an exemplary embodiment of the claimed invention. The MADPPROD optimizer 1240 used 114 attributes available from the SID 1300, which achieved a production accuracy of 97% using historical data. Appendix 3 is a glossary of the 184 structured attributes and many more unstructured attributes used to select the 114 most important attributes for predicting production.

In accordance with an exemplary embodiment of the claimed invention, the MAPPROD optimizer 1240 uses a Machine Learning optimizer to compute the Importance Weights for the hundreds of multi-dimensional attributes that represent all the data available at each time as the well proceeds, from before spud, to after drilling and finally after completion. In accordance with an aspect of the claimed invention, Table 3 illustrates the Importance Weights of the 114 attributes in the reduction to practice study, combining the data common to all analyzed wells from the system integration database 1300, which contains 185 digitally structured attributes and numerous unstructured textual attributes defined in the glossary of Appendix 3. FIG. 10 illustrates the top 20 Importance Weights of Table 3. In accordance with an exemplary embodiment of the claimed invention, FIGS. 11A-C illustrate the Importance Weights of the 114 attributes, when convolved with the specific attributes of each well contributed to a Production Prediction for Oil, Gas, and Water of 97%+/−2.7%.

In accordance with an exemplary embodiment of the claimed invention, the MAPPROD optimizer 1240 convolves the Importance Weights for all wells in each study area f with g which is each attribute value specific to the well for which future production of oil, gas and water is being calculated, wherein f*g is an integral transform of the product of the two functions as attributes specific to that well under study. The integral transform then predicts the future production of the well under study before the oil and gas are delivered to the surface and uses future production to calculate an accuracy of that initial forecast.

FIGS. 11A-D illustrate the MAPPROD predictions for oil, gas, and water production using the dataset of 0 Root Mean Square accuracy varied from +/−2.7% for 114 attributes to +/−11% for 32 attributes. In accordance with an exemplary embodiment of the claimed invention, as shown in FIGS. 11A-C, the MAPPROD optimizer 1240 convolved the Importance weights using the 114 attributes in Table 3 with the 156 wells in the reduction to practice dataset, resulting in production predictions for oil, gas and water that were found to be 97% accurate compared to the initial forecast. As shown in FIG. 11D, the Root Mean Square Error (RMSE) of the predicted versus actual production forecasts increased from +/−11% for 32 MAPGEORES attributes, to 9% for 45 MAPGEORES plus MAPDRILL attributes, to 7% for 62 MAPFRAC added attributes, to 6% when FracClass attributes were added, and finally to 2.7% when all resulting attributes that were available before first oil was produced to the surface.

As exemplary shown in FIG. 12, the pipeline gathering system 1600 is critical to deliver the production to market, the MAPGATHER analytic engine 1250 correlates cause-and-effect events between producing wells, production pads and pipeline gathering and compression station events 1251 that might be mitigated by preventive maintenance, day-ahead forecasts of available gathering system capacity, and changes to loops that may be created within the gathering system to alleviate congestion and prevent choke points. This information can be conveyed automatically by self-driving, autopilot and/or other autonomous means to the controller for management of the pipeline gathering system.

For compressor stations 1251 within the pipeline gathering system 1600, the MACGATHER analytic engine 1250 continuously analyzes clusters of correlation in compressors, engines, and separator performances, and prescribes maintenance routines that need to be changed. In accordance with an exemplary embodiment of the claimed invention, the MAPGATHER analytic engine 1250 provides an analytical solution that analytically analyzes the effects of weather on incidence reports, day and night scheduling, inspections, etc. and automatically conveys this information by self-driving, autopilot and/or other autonomous means to the controller for management of the pipeline gathering system. The MAPGATHER analytic engine 1250 generates a composite Tornado plot for seasons, wet versus dry and hot versus cold. Forecasting of day-ahead and week-ahead pipeline gathering system capacity by the MAPGATHER subystem 1250 leads to the identification of maintenance that will prevent the need to shut-in wells because of excessive gathering system capacity. The MAPGATHER analytic engine 1250 ranks section by section of good to bad performing pipeline sections (by section) allows forecasting of susceptibility to liquids trapping, actual versus planned pigging success, witches hat problem events before they happen, and condensate restrictions needed to reduce actual/predicted production.

As exemplary shown in FIG. 12, the pipeline gathering system 1600 may not be pigging optimally. In accordance with an exemplary embodiment of the claimed invention, the MAPGATHER analytic engine 1250 predicts, and then prescribes better pigging schedules. For example, the MAPGATHER analytic engine 1250, detects predictable pressures that build up repeatedly at specific locations 1252 because of too much liquids accumulation in topographic low points that are prescribed for higher levels of Pigging surveillance. This information is automatically conveyed by self-driving, autopilot and/or other autonomous means to the controller for management of the pipeline pigging system.
